Structure Gene (SG) I/O
Python package interfacing VABS and SwiftComp. The package is developed based on meshio, which is used for converting meshing data.
The package can be used to
- read/write SG data from/to different formats
- convert SG/mesh data between different formats
- read structural property from VABS/SwiftComp output
- create 1D SG from layup input
Supported data formats:
- for complete SG data
- VABS, SwiftComp, Abaqus
- for mesh data only
- all formats supported by meshio
A structure gene (SG) is defined as the smallest mathematical building block of a structure.1 A cross-section (CS) is a type of 2D SG.

Suppose a cross-section has been built in Abaqus and output to cross-section.inp.
To convert the data to the VABS input (Timoshenko model) cross-section.sg:
sgio convert cross-section.inp cross-section.sg -ff abaqus -tf vabs -m bm2
